Simplicity

Simplicity is a 21-level megawad created for ZDoom by Melissa McGee (Agent Spork), split between two episodes. The mod features a series of fairly short maps, a part of which are speedmaps, and utilizes a lot of ZDoom features, but despite this it strongly adheres to vanilla gameplay, aiming to offer a fast-paced and simple experience as opposed to more elaborate total conversions (and hence the name). It was originally released on the 25th of October 2005.

Two years later, on the 7th of September 2007, an updated version of the megawad called Ultimate Simplicity was released, which among other things improved some of the already existing maps, replaced some of them entirely and offloaded the scrapped maps into a third episode called the Director's Cut.

Simplicity received one of the 12th Annual Cacowards.
